Dumbarton Castle

I read this morning that on this date in 1548 Mary, Queen of Scots left Dumbarton Castle to travel to France to marry the Dauphin Francis. It was 1561 before she returned to Scotland.
So it seemed appropriate to go an extra junction along the motorway on the way home to capture today's Blip.
